The incompetent with nothing to do can still make a mess of it. - Laurence J. Peter

Before publishers' blurbs were invented, authors had to make their reputations by writing.

In time I saw that all such cases had a common feature. The employee had been promoted from a position of competence to a position of incompetence. I saw that, sooner or later, this could happen to every employee in every hierarchy.

Dr. Peter observed that one reason so many employees are incompetent is that the skills required to get a job often have nothing to do with what is required to do the job itself. The skills required to run a great political campaign have little to do with the skills required to govern.
